RESUMO

BACKGROUND: Liver resection is pivotal in treating incidental gallbladder cancer (IGBC). However, the adequate volume of liver resection remains controversial. METHODS: A cross-sectional retrospective analysis was performed on resected IGBC patients between 1999 and 2018. Morbidity was evaluated according to the Clavien-Dindo classification. The theoretical volume of a 2-cm and 1.5-cm wedge liver resection was calculated (105 cm3 and 77.5 cm3, respectively) and used as reference. Overall survival (OS) was estimated using Kaplan-Meier and Cox regression analyses. RESULTS: Among 111 patients re-resected for IGBC, 84 provided sufficient data to calculate liver resection volume. Patients with a resection volume ≥ 105 cm3 had a higher rate of overall morbidity (P = 0.001) and length of stay (P = 0.012), with no difference in mortality. There was no significant difference in OS according to residual cancer or T-category. A resection volume ≥ 77.5 cm3 was more frequent in T ≥ 3 than in T1-2 patients (P = 0.026), and residual cancer was higher (P = 0.041) among patients with ≥ 77.5 cm3 resected. Cox multivariate regression showed that residual cancer (HR = 11.47, P < 0.001), perineural/lymphovascular invasion (HR = 2.48, P = 0.021), and Clavien-Dindo ≥ IIIa morbidity (HR = 5.03, P = 0.003) predict worse OS, but not liver volume resection. CONCLUSION: There are no significant differences in OS based on resected liver volume of IGBC, when R0 is achieved. There is a significant difference in morbidity and length of stay when liver wedges are ≥ 105 cm3, which is lost when analyzed by Clavien-Dindo ≥ IIIa. A 77.5-105 cm3 resection is indicated in ≥ T3 patients, minimizing morbidity risk, while addressing concerns of overall survival.

RESUMO

BACKGROUND: Hepatocellular carcinoma (HCC) is the sixth most common cancer in the world. Surgery is the treatment of choice in stages 0 and A in the Barcelona Clinic Liver Cancer classification. A minimally invasive technique in this scenario has the advantage of reducing postoperative pain, blood loss, and hospital stay. We present our experience and outcomes in laparoscopic liver resection in HCC. METHODS: Retrospective descriptive analysis from all patients who underwent laparoscopic liver resection for HCC in our center between August 2006 and December 2020. RESULTS: Laparoscopic liver resection for HCC was performed in 20 patients. The median age was 70 years, and the male gender was 75%. Sixteen patients had chronic liver disease, and 87.5% were Child A. The most common liver resection was the non-anatomical (45%). 30-day morbidity was 15%, without the need for reintervention. We had no 30-day mortality and postoperative liver failure. Negative margins were achieved in 90% of patients. Median disease-free survival and overall survival were 25 and 40.5 months, respectively. CONCLUSION: Laparoscopic liver resection for the treatment of HCC in our series is safe, with no 30-day mortality, low incidence of complications, no postoperative liver failure, and suitable medium- and long-term oncological results.

RESUMO

In Chile, colorectal cancer ranks third in incidence and fifth in mortality. Half of these patients have liver metastases at the diagnosis, and only 30% of them are resectable. Despite the development of many complex hepatobiliary procedures to achieve the total resection of metastases, the long-term survival with these techniques is not good. Liver transplantation is an alternative to treat unresectable liver metastasis from colorectal cancer with a good outcome. Several prognostic scores allow the selection of patients with good tumor biology. These patients have better overall and disease-free survival after liver transplantation. The use of immunosuppressive treatment doesn't increase recurrence, and even the pattern of tumor growth is slower in liver transplant recipients. The purpose of this review is to summarize the current evidence in this topic and to highlight the need for a formal protocol for liver transplantation for unresectable colorectal liver metastases, using living donors or marginal grafts to avoid competition with the rest of the national waiting list.

RESUMO

BACKGROUND: Vena cava (VC) involvement in kidney tumors occurs in 4 to 10% of cases, and is associated with a higher mortality. Nephrectomy with thrombectomy of the VC, performed by a multidisciplinary team, improves survival. AIM: To report a series of consecutive nephrectomies with caval thrombectomy performed in an academic center. PATIENTS AND METHODS: We report 32 patients with cT3b and 3c renal tumors, who underwent radical nephrectomy with VC thrombectomy between 2001 and 2021. A descriptive analysis of clinical, surgical and pathological variables was performed. Overall survival (OS) and cancer-specific survival (CSS) was calculated using Kaplan-Meier curves. RESULTS: The mean tumor size was 9.7 cm. According to Mayo classification 3/32 (9%) patients had a type I thrombus, 10/32 (31%) had a type II thrombus, 8/32 (25%) had a type III thrombus, and 5/32 (16%) had a type IV thrombus. The mean bleeding was 2000 cc. There was one intraoperative death. Nineteen percent of patients had complications >= 3 according to Clavien-Dindo classification. Reoperations occurred in 9%. Pre and postoperative creatinine levels were 1.17 and 1.91 mg/dl respectively (p < 0.01). Pre and postoperative Hematocrit levels were 47.9 and 31% respectively (p = 0.02). Sixty six percent of tumors were clear cell renal cancer, 9% were papillary and 3% were chromophobic. Mean OS was 10 months. Two-year SCE was 40%. CONCLUSIONS: Our results are similar to those reported elsewhere. Despite being an unusual pathology, the surgical technique has been improving, thanks to the multidisciplinary work of urologists and surgeons.

RESUMO

BACKGROUND: The risk of neoplasia in gallbladder polyps seems to be low, but the evidence from populations at high-risk of gallbladder cancer is limited. We aimed to estimate the risk and to identify the factors associated with neoplastic polyps in a high-risk Hispanic population. METHODS: A retrospective cohort was recruited between January 2010 and December 2019 at a Chilean university center. Multivariate survival analyses were conducted. Fine-Gray models were fitted to account for competing risks. Covariate adjustment was conducted using propensity scores. The main outcome was the development of gallbladder adenomas or adenocarcinoma. RESULTS: Overall, 748 patients were included, 59.6% underwent cholecystectomy. The median follow-up of patients not subjected to cholecystectomy was 54.7 months (12-128.6 months). Seventeen patients (2.27%) developed the outcome. After adjustment by age, sex, intralesional blood flow, lithiasis and gallbladder wall thickening, only polyp size (≥10 mm, adjusted-HR: 15.01, 95%CI: 5.4-48.2) and number of polyps (≥3 polyps, adjusted-HR: 0.11, 95%CI: 0.01-0.55) were associated with neoplasia. CONCLUSION: In a Hispanic population at high-risk for gallbladder cancer, gallbladder polyps seem to have a low risk of neoplasia. Polyp size was the main risk factor, while having multiple polyps was associated with an underlying benign condition.

RESUMO

In patients with actively bleeding gastric varices, the treatment of choice is the endoscopic use of sclerosing agents such as cyanoacrylate. We report a 69-year-old man who, after being treated with cyanoacrylate, suffered from recurrent febrile episodes. After an extensive study and broad-spectrum antibiotic treatment, discarding other presumably infectious focus, the superinfection of the cyanoacrylate plug was suspected, and its surgical removal was decided. A partial gastrectomy of the gastric fundus, a splenectomy, and a distal pancreatectomy were performed. The patient evolved without fever and without new episodes of bacteremia, but with decompensation of his cirrhosis manifested by ascites, spontaneous bacterial peritonitis, pneumonia, and collections in the pancreatic bed. These complications were managed with medical treatment consisting in a long course of broad-spectrum antibiotics. Thereafter, the patient evolved satisfactorily.

RESUMO

INTRODUCTION AND AIM: The Balance of Risk (BAR) Score, a simple scoring system that combines six independent donor and recipient variables to predict outcome after liver transplantation (LT), was validated in a large U.S./European cohort of patients. This study aims to assess the performance of the BAR score to predict survival after liver transplantation and determine the factors associated with short and long-term survival in Latin-American patients. MATERIAL AND METHODS: A retrospective cohort study was performed in 194 patients [112 (55.4%) males; mean age 52±14 years] who underwent 202 LT during the period 2003-2015. Demographic, clinical, pathological and surgical variables, as well as mortality and survival rates, were analyzed. The BAR score was investigated through a receiver operating characteristics (ROC) curve with the calculation of the area under the curve (AUC) to evaluate the predictive score power for 3-month, 1 and 5-year mortality in a matched donor-recipient cohort. Youden index was calculated to identify optimal cutoff points. RESULTS: The AUC of BAR score in predicting 3-month, 1-year and 5-year mortality were 0.755 (CI95% 0.689-0.812), 0.702 (CI95% 0.634-0.764) and 0.610 (CI95% 0.539-0.678) respectively. The best cut-off point was a BAR score ≥15 points. In the multivariate analysis BAR score <15 was associated with higher survival rates at 3 months and 1 and 5-years. CONCLUSIONS: BAR score <15 points is an independent predictor of better short and long-term survival in Latin-American patients undergoing LT. The BAR scoring system has an adequate diagnostic capacity allowing to predict 3 and 12-month mortality.

RESUMO

Due to blood derivative requirements, many patients with hemophilia were exposed to Hepatitis C virus infection (HCV) before the availability of HCV testing. We report a 46-year-old male with Hemophilia A with a hepatitis virus C infection since 2004 causing a cirrhosis. Due to a hepatopulmonary syndrome, he received a liver allograph using a factor VIII replacement protocol, after eradicating the virus C. He had a good postoperative evolution, and no more factor VIII was required after transplantation until his last assessment.

RESUMO

BACKGROUND: Liver transplantation (LT) is an option for people with liver failure who cannot be cured with other therapies and for some people with liver cancer. AIM: To describe, and analyze the first 300 LT clinical results, and to establish our learning curve. MATERIAL AND METHODS: Retrospective cohort study with data obtained from a prospectively collected LT Program database. We included all LT performed at a single center from March 1994 to September 2017. The database gathered demographics, diagnosis, indications for LT, surgical aspects and postoperative courses. We constructed a cumulative summation test for learning curve (LC-CUSUM) using 30-day post-LT mortality. Mortality at 30 days, and actuarial 1-, and 5-year survival rate were analyzed. RESULTS: A total of 281 patients aged 54 (0-71) years (129 women) underwent 300 LT. Ten percent of patients were younger than 18 years old. The first, second and third indications for LT were non-alcoholic steatohepatitis, chronic autoimmune hepatitis and alcoholic liver cirrhosis, respectively. Acute liver failure was the LT indication in 51 cases (17%). The overall complication rate was 71%. Infectious and biliary complications were the most common of them (47 and 31% respectively). The LC-CUSUM curve shows that the first 30 patients corresponded to the learning curve. The peri-operative mortality was 8%. Actuarial 1 and 5-year survival rates were 82 and 71.4%, respectively. CONCLUSIONS: Outcome improvement of a LT program depends on the accumulation of experience after the first 30 transplants and the peri-operative mortality directly impacted long-term survival.

RESUMO

Garengeot's hernia corresponds to the presence of the appendix within a femoral hernia, associated or not with acute appendicitis. The diagnosis of this uncommon situation is usually done during surgery. Furthermore, the clinical presentation as necrotizing fasciitis is a rare condition. We report a 54 years old obese hypertensive woman with rheumatoid arthritis of 40 years of evolution treated with methotrexate and prednisone. She consulted for pain and erythema in the right inguinal region. Laboratory revealed leukocytosis and an elevated C-reactive Protein. Suspecting a cellulitis, the patient was admitted for antimicrobial therapy. A pelvic magnetic resonance imaging showed a perforated acute appendicitis in an inguinal hernia with extensive pelvic cellulitis associated with signs of fasciitis. At surgery, an extensive groin and pubic fasciitis was evident, with a necrotic and perforated appendix within a femoral hernia. Surgical debridement, open appendectomy, and femoral hernioplasty without mesh were carried out. Vacuum-assisted closure was installed in the coverage defect. Three surgical debridement procedures were required for the closure of the wound. Two weeks after the first surgical procedure, the patient was discharged in good condition. During the follow-up, she evolved with a surgical wound dehiscence, which was managed with wound dressings until closure.

RESUMO

Abstrac: Before the advent of highly active antiretroviral therapy (HAART), patients infected with human immunodeficiency virus (HIV) were considered as having an absolute contraindication for liver transplantation (LT). Considering the increased life expectancy in HIV positive patients under HAART and the improvements in the management of graft recipients, these patients are now suitable for carrying out transplants in selected cases. We report a 26 years old HIV positive male who developed acute liver failure possibly caused by drug induced liver injury who underwent a successful liver transplantation.

RESUMO

BACKGROUND: The laparoscopic approach for the treatment of gastric tumors has many advantages. AIM: To evaluate the results of a laparoscopic gastrectomy program developed in a public hospital. PATIENTS AND METHODS: Retrospective review of epidemiological, perioperative and follow-up data of patients who were treated with a laparoscopic gastrectomy due to gastric tumors between 2006 and 2013. A totally laparoscopic technique was used for all cases. Complications were evaluated according to the Clavien-Dindo classification. RESULTS: Fifty one patients, aged 65 (36-85) years, underwent a laparoscopic gastrectomy. In 22 patients a total gastrectomy was performed. Conversion rate to open surgery was 8%. Operative time was 330 (90-500) min and bleeding was 200 (20-500) ml. Median hospital stay was 7 (3-37) days. Postoperative morbidity was present in 17 (33%) patients, 3 (6%) patients had complications grade 3 or higher and one patient died (1.9%). Tumor pathology was adenocarcinoma in 39 patients. A complete resection was achieved in 97%. Twenty nine patients (74%) with gastric adenocarcinoma had early gastric cancer and 84% of patients were in stage one. Median lymph node count was 24. Median follow-up was 26 (1-91) months. There was no cancer related mortality among patients subjected to a curative resection. Overall survival for patients with adenocarcinoma was 92% at 3 years. CONCLUSIONS: This study supports the feasibility and safety of a laparoscopic gastrectomy program in a public hospital; with low morbidity, adequate lymph node dissection and long-term survival. This approach must be considered an option for selected patients with gastric cancer.

RESUMO

Portal vein thrombosis is a rare complication after laparoscopic sleeve gastrectomy, a widely performed bariatric surgery procedure. Occasionally, the development of portal vein thrombosis can progress to more severe conditions, including portal hypertension and cavernomatosis, thereby presenting a complex and challenging clinical scenario. The management of such complications often requires careful consideration; however, surgical intervention in the form of a splenorenal shunt is an exceptional indication. We present the case of a 33-year-old female patient who had previously undergone laparoscopic sleeve gastrectomy in 2014 and subsequently developed portal thrombosis, followed by cavernomatosis and associated complications of portal hypertension. A proximal splenorenal shunt procedure and splenectomy were successfully performed to manage portal hypertension. The presentation of this clinical case aims to contribute to the available evidence and knowledge surrounding this rare and challenging pathology.

RESUMO

OBJECTIVE: The aim of this study was to assess the risk factors associated with 30-day hospital readmissions after a cholecystectomy. METHODS: We conducted a case-control study, with data obtained from UC-Christus from Santiago, Chile. All patients who underwent a cholecystectomy between January 2015 and December 2019 were included in the study. We identified all patients readmitted after a cholecystectomy and compared them with a randomized control group. Univariate and multivariate analyses were conducted to identify risk factors. RESULTS: Of the 4866 cholecystectomies performed between 2015 and 2019, 79 patients presented 30-day hospital readmission after the surgical procedure (1.6%). We identified as risk factors for readmission in the univariate analysis the presence of a solid tumor at the moment of cholecystectomy (OR = 7.58), high pre-operative direct bilirubin (OR = 2.52), high pre-operative alkaline phosphatase (OR = 3.25), emergency admission (OR = 2.04), choledocholithiasis on admission (OR = 4.34), additional surgical procedure during the cholecystectomy (OR = 4.12), and post-operative complications. In the multivariate analysis, the performance of an additional surgical procedure during cholecystectomy was statistically significant (OR = 4.24). CONCLUSION: Performing an additional surgical procedure during cholecystectomy was identified as a risk factor associated with 30-day hospital readmission.


OBJETIVO: El objetivo de este estudio fue evaluar los factores de riesgo asociados al reingreso hospitalario en los primeros 30 días post colecistectomía. MÉTODOS: Estudio de casos-controles con datos obtenidos del Hospital Clínico de la UC-Christus, Santiago, Chile. Se ­incluyeron las colecistectomías realizadas entre los años 2015-2019. Se consideraron como casos aquellos pacientes que reingresaron en los 30 primeros días posterior a una colecistectomía. Se realizó un análisis univariado y multivariado de diferentes posibles factores de riesgo. RESULTADOS: De un total de 4866 colecistectomías, 79 pacientes presentaron reingreso hospitalario. Los resultados estadísticamente significativos en el análisis univariado fueron; tumor sólido al momento de la colecistectomía (OR = 7.58) bilirrubina directa preoperatoria alterada (OR = 2.52), fosfatasa alcalina preoperatoria alterada (OR = 3.25), ingreso de urgencia (OR = 2.04), coledocolitiasis al ingreso (OR = 4.34) realización de otros procedimientos (OR = 4.12) y complicaciones postoperatorias. En el análisis multivariado sólo la realización de otro procedimiento durante la colecistectomía fue estadísticamente significativa (OR = 4.24). CONCLUSIÓN: La realización de otros procedimientos durante la colecistectomía es un factor de riesgo de reingreso hospitalario en los 30 días posteriores a la colecistectomía.

RESUMO

Gastric lipoma is a rare benign gastric tumor. We report a 62-year-old man, who presented with abdominal pain, vomiting and weight loss. An upper gastrointestinal endoscopy showed a gastric antral, submucosal tumor. Abdominal ultrasound and computed tomography revealed a large antral lesion with content of high echogenicity and fat density, measuring 11 x 6 cm. The patient was treated with a laparoscopic distal subtotal gastrectomy, and a Roux-en-Y reconstruction. The patient had no postoperative morbidity, was started on a liquid diet on the third postoperative day and was discharged on the third postoperative day. The pathological study revealed a gastric lipoma with clear margins. This laparoscopic procedure represents a good alternative in the treatment of this benign gastric tumor.

RESUMO

INTRODUCTION AND IMPORTANCE: Portal biliopathy (PB) is an abnormality of the biliary tree wall due to extrahepatic portal hypertension. Among the complications of portal biliopathy are digestive bleeding, jaundice, and cholangitis. Surgical treatment is an exception when medical management is not possible. CASE PRESENTATION: This is a case series study of four patients with severe PB complications requiring surgical management in our center from 2005 to 2016. Two of them had previous surgical procedures related to portal hypertension. All presented with severe biliary stenosis and recurrent cholangitis, and two also had massive upper gastrointestinal bleeding. Because of endoscopic management failure, a Roux-en-Y hepaticojejunostomy was performed in all cases. Two patients presented morbidity Clavien-Dindo>IIIA, requiring reoperation. During follow-up, no one developed other complications related to PB. DISCUSSION: Surgical treatment for PB complications is a challenge and mainly implies a portosystemic shunt as a first step. When it fails, an alternative is perform a biliodigestive anastomoses, with high risk of bleeding given the prominent collaterals present in the hepatoduodenal pedicle secondary to portal cavernomatosis. CONCLUSION: Our patients after YRGB didn't present new complications due to PB. The surgery could be a definite solution for PB complications. It has only been made for selective cases because it implies high complexity and risk.

RESUMO

BACKGROUND: Hepatolithiasis is a prevalent disease in Asia but rare in Western countries. An increasing number of cases have been reported in Latin America. Liver resection has been proposed as a definitive treatment for complete stone clearance. The aim of this study was to evaluate the postoperative outcomes of liver resection for the treatment of hepatolithiasis in 2 large hepatobiliary reference centers from South America. METHODS: We conducted a retrospective descriptive analysis from patients with hepatolithiasis who underwent liver resection between November 1986 and December 2018, in 2 Latin-American centers in Chile and Brazil. RESULTS: One hundred forty-nine patients underwent liver resection for hepatolithiasis (72 in Chile, 77 in Brazil). The mean age was 49 years and most patients were female (62.4%). Hepatolithiasis was localized in the left lobe (61.7%), right lobe (24.2%), and bilateral lobe (14.1%). Bilateral lithiasis was associated with higher incidence of preoperative and postoperative cholangitis (81% vs 46.9% and 28.6% vs 6.1%) and need for hepaticojejunostomy (52.4%). In total, 38.9% of patients underwent major hepatectomy and 14.1% were laparoscopic. The postoperative stone clearance was 100%. The 30-day morbidity and mortality rates were 30.9% and 0.7%, respectively. Cholangiocarcinoma was seen in 2 specimens, and no postoperative malignancy were seen after a median follow-up of 38 months. Fourteen patients (9.4%) had intrahepatic stones recurrence. CONCLUSIONS: Liver resection is an effective and definitive treatment for patients with hepatolithiasis. Bilateral hepatolithiasis was associated with perioperative cholangitis, the need for hepaticojejunostomy, and recurrent disease. Resection presents a high rate of biliary tree stone clearance and excellent long-term results, with low recurrence rates and low risk of malignancy.

RESUMO

BACKGROUND: The increasing prevalence of obesity and need for bariatric surgery as well as the expanding use of living donors for liver transplantation means that potential donors could present with this surgical history. We present 4 cases of liver donors with previous bariatric surgery in our living donor liver transplant program. METHODS: A retrospective descriptive analysis of patients with a bariatric surgery history who underwent right hepatectomy in our living donor liver transplant program is presented. RESULTS: Case 1: A 53-year-old man with body mass index (BMI) of 33 who underwent laparoscopic sleeve gastrectomy (LSG). Pretransplant BMI was 21.5. Case 2: A 46-year-old woman with a BMI maximum of 40.8 who underwent LSG and required conversion to Roux-en-Y gastric bypass. Pretransplant BMI was 35.1. Case 3: A 53-year-old woman with a BMI maximum of 31.6 who underwent LSG. Pretransplant BMI was 24.2. Case 4: A 38-year-old man with a BMI maximum of 41.5 who underwent Roux-en-Y gastric bypass 6 years before the hepatectomy. Pretransplant BMI was 29.4. No complications were observed. Average operative time was 367.5 minutes, with a hospital stay of 5.8 days and 100% graft survival to date. DISCUSSION: Utilization of selected donors with previous bariatric surgery appears to be a safe option and increases the donor pool.

RESUMO

Vasculobiliary injuries (VBI) caused by cholecystectomies are infrequent but extremely serious. We report a case of a severe VBI successfully treated at our center. A 22-year-old woman underwent an open cholecystectomy as treatment for acute cholecystitis and bile duct stones. She was transferred to our center on postoperative Day 4 because of progressive jaundice and encephalopathy. After a proper investigation, we found an extreme VBI with infarction of the right hepatic lobe associated with complete interruption of the portal vein and proper hepatic artery flows and full section of the common hepatic duct. Right hepatectomy with portal-Rex shunt revascularization of the left hepatic lobe and Roux-en-Y hepaticojejunostomy to the left hepatic duct was done. The patient was discharged on the 60th postoperative day. Discussion: This case shows the successful surgical treatment of a severe cholecystectomy's VBI, avoiding an emergency liver transplant.
